The power steering fluid reservoir is a relatively simple part that does a single job in your car. Despite its simplicity, it’s an indispensable part of the power steering system. If something goes wrong with the fluid reservoir, you’ll find it more difficult or even impossible to control your vehicle.
Below are the most common symptoms of a faulty power steering reservoir:
One issue that the power steering fluid reservoir might develop is a fluid leak, although reservoir leaks are rather uncommon.
The power steering reservoir stores hydraulic fluid that feeds the pump’s inlet port via gravity, and there will typically be a large hose on remote mounted reservoirs or an o-ring on the pump-mounted ones.
Leaks deplete the available hydraulic fluid. While you can refill the reservoir, the leaky part will continue losing fluid. A shortage of fluid will reduce power steering assist.
There are ways to identify the presence of a leak in the power steering fluid reservoir. Inspect the ground beneath your car for amber, red, or reddish-brown fluid. Depending on the leak’s size and how long it’s been dripping, you might find a few drops of power steering fluid or an entire puddle.
Do you hear a high-pitched whining and feel reduced or jerky assist whenever you turn the steering wheel or go around a corner? Whining noises can indicate a leaky power steering fluid reservoir or a clogged screen as discussed in the opening paragraph.
When the power steering pump doesn’t get the fluid it needs for whatever reason, cavitation occurs and the fluid becomes aerated, which reduces assist and causes the pump to be noisy.
You can temporarily reduce the noise by filling the power steering fluid reservoir. However, the relief will only last until the hydraulic fluid drops to low levels again. But if the aeration has filled the entire system, you may find that the pump still whines even after you fill the reservoir. Also, remember not to forget to check the screen mentioned in the opening section.
Without sufficient power steering fluid, your vehicle becomes less responsive to your control inputs. The steering wheel becomes more resistant to turning, forcing you to expend more effort to operate it.
Avoid driving your car if its power steering fluid level becomes too low. If an emergency forces you to hit the road despite this issue, fill the power steering fluid reservoir before starting your vehicle. It won’t stop the leaks, but it might restore enough power steering to get your vehicle somewhere it can receive repairs.
The power steering fluid reservoir is the container that stores the hydraulic fluid used by your vehicle’s power steering system.
It’s the hydraulic fluid that flows through your car’s power steering system. Power steering fluid is pressurized and has lubricative properties.
The purpose of power steering fluid is to establish a hydraulic link between the steering wheel and the front wheels. It amplifies the pressure you apply to the steering wheel and transmits that enhanced force. The power steering pump has the largest pulley driven by the belt due to the power required to operate the pump, which can produce up to 1500 psi.
Furthermore, power steering fluid also acts as a lubricant. It reduces friction between the steering system’s moving parts. It also prevents corrosion and foaming, improving parts’ performance and extending their service lives.
Despite what you might think, power steering fluid isn’t highly flammable. To be classified as flammable, a liquid must have a flash point lower than 100° Fahrenheit. The flash point is the lowest temperature that an outside ignition source can ignite the vaporized liquid.
Power steering fluid has a flash point of around 400°F. This makes it a combustible, not a flammable. Combustibles can burn, but their vapor won’t catch fire at temperatures below 100°F.
However, it’s still not safe to ignore leaked fluid. People might slip on it and suffer injuries.
If power steering fluid has leaked on the ground, clean it immediately to prevent a potential fire hazard. Spread absorbent material over the stain to soak up the fluid.
Pour strong laundry detergent over the power steering fluid stain. Let it stand for the night before scrubbing and rinsing it. If you have trisodium phosphate, spread it on the stained surface. Alternatively, mix it with water and pour the solution on the stain.
While power steering fluid isn’t flammable, how hot can it get before things go wrong? Many power steering fluids boil when their temperature exceeds 600° F. Fortunately, the power steering operates at much lower temperatures.
Some experts recommended 180° Fahrenheit as the optimal operating temperature for power steering fluid in high-performance machines like racing cars. They cite 250° as the highest safe temperature. Ordinary vehicles will usually run at somewhat lower temperatures.
While it’s possible to fix some of the issues with the power steering reservoir, you might have to replace the entire part. Be prepared to pay as low as $10 and as high as $190 for a replacement reservoir. The price tag can vary depending on factors ranging from the product’s manufacturer, your vehicle’s details, and the size of the new part.
It’s important to replace your vehicle’s power steering fluid reservoir as soon as you’ve confirmed that it is cracked or leaking. Luckily, you can get a replacement that’s compatible with your vehicle easily thanks to CarParts.com.
